Title: Photomask for semiconductor device
Inventor: SAKAMOTO MITSUO
IPC: G03F1/54
Filed: 1984-12-25
Abstract: PURPOSE:To enable the use of a photomask in the far ultraviolet region and to improve work efficiency by forming the fine pattern of the thin film of a light shielding metal and the pattern of the thin film of a metallic oxide which is translucent in the visible region and shields the rays of light in the required wavelength region on the surface of a substrate. CONSTITUTION:The thin metallic film for forming a light shielding fine pattern such as the pattern 2 of a thin Cr film and the pattern 4 of the thin film of the metallic oxide which is translucent in the visible region and shields the rays of light in the required wavelength region are formed on the surface of a substrate 1 to obtain a photomask used in the production of a semiconductor device by a photomechanical process. Ferric oxide is preferably used as the metallic oxide of the thin film 4. The resulting photomask has high contrast and resolving power peculiar to the thin Cr film and gives high work efficiency owing to the translucency of the thin ferric oxide film in the visible region. Since the thickness of the oxide film is only about several thousand Angstrom , blurring is hardly caused by diffraction or interference. The photomask can be used for a long period because of the high surface hardness.

Abstract: PURPOSE: To reduce filming caused by developer, and to scatter the developer left after transfer so as to obtain an excellent image by specifying relation among the rotating direction of a rotary brush, the contact nip width of the brush with an electrostatic latent image carrier and the thickness of a brush layer. CONSTITUTION: The brush layer 22 of the rotary brush 21 comes in contact with the surface of a photoreceptor drum 1 by a fixed push-in amount (biting amount), and the contact nip width N thereof and the thickness (t) of the brush layer are set to satisfy the condition, 20<=(N)<2> /t<=35. In such a case, the thickness of the brush layer is the thickness of a pile layer. The rotating direction (c) of the brush 21 is reverse to the rotating direction (a) of the drum 1, and the rotating direction of the brush 21 is what is called a follow direction with respect to the rotating direction of the drum 1 concerning the moving direction of the contact part of the brush 21 with the drum 1.  Therefore, even when transfer efficiency is low, for example, about 60%, and even under high temperature and high humidity environment where the transfer efficiency is lowered, the filming caused by the developer is eliminated and the developer left after transfer is scattered by the brush 21, thereby improving image quality.

Title: Pos terminal equipment
Inventor: NOMURA YOJIRO
IPC: G07G1/00
Filed: 1990-10-16
Abstract: PURPOSE:To prevent the degradation in service to shopping customers by transmitting sales data to a master machine at the time of the absence of shopping customers and interrupting transmission at the time of appearance of shopping customers. CONSTITUTION:When a shopping customer puts a shopping basket, in which goods are put, on a sacker table, a weight sensor monitor means 8 detects it to find the existence of the shopping customer. The weight sensor monitor means 8 reports this state to a sales data transmission means 9 to determine whether the transmission processing to the master machine is possible or not. Though the sales data transmission means 9 tries to start transmission to the host machine after the end of sales registration of one customer, transmission is started if the shopping basket in which goods are put by a second shopping customer is not detected by the weight sensor monitor means 7, but the equipment prepares for sales registration processing of the next shopping customer if it is not detected. When the next shopping basket is detected on the way of transmission, transmission is interrupted to concentrate the equipment to the sales registration work. Thus, the degradation in service to shopping customers is prevented.

Title: Two-way bus interface device
Inventor: ITSUGAYA KINJI
IPC: H04L29/08
Filed: 1988-11-04
Abstract: PURPOSE:To prevent the transmission of an undesired pulse for a two-way bus even if a power voltage reaches an operation unguarantee voltage by interfacing a signal outputted from an open collector type gate for an external two-way bus. CONSTITUTION:A signal from an input terminal DIR inputted via an inverter 1 and a signal from an input terminal INH are inputted to an AND gate 2. A control signal is outputted to a control terminal of a three-state buffer 4. In this case, when a switch or the like connecting to the input terminal INH is closed to give a ground level, the 3rd input terminal of an open collector type three-input NAND gate 3 is connected to ground via switch. Thus, even if the power voltage reaches an operation unguarantee voltage, the output terminal of the open collector type three-input NAND gate 3 is always at a high level and no undesired pulse is sent to an input output terminal B of the two-way bus interface.

Title: Auxiliary superconductive composite wire and its manufacture
Inventor: KATOU KOUKI
IPC: B21F15/02
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To enhance the quality of a superconductive composite wire by forming a conductor as initial winding from Ag-Au-Mn alloy, thereby heightening the mechanical strength of the initial winding conductor to ensure enhancement of the yield and the easiness in works, and also reducing the thermal conductivity. SOLUTION: An auxiliary superconductive composite wire for use as a reserve consists of a laminate 4 of superconductive element wires 1 of such a structure that a metal film 3B is provided on the peripheral surface of a superconductive core 3A made of a superconductive material. An initial winding conductor 2 made of Ag-Au-An alloy is wound on the periphery of this laminate 4 at a certain pitch, followed by fixation and a prescribed heat treatment, and thus the intended superconductive composite wire is obtained. The Au and Mn contents of the conductor 2 should be 0.01-30at.% and 0.01-5at.%, respectively, and thereby the low thermal conductivity and tensile strength are improved. This should enhance the quality of the resultant composite wire, give a good yield, and improve the easiness in works of initial winding.
